chore: use custom thread pool for vaadin-dev-server tasks (#20795)

* chore: use custom thread pool for vaadin-dev-server tasks

Vaadin dev-server executes long-running tasks (e.g. npm install) using
the common ForkJoin pool. This can cause a slow startup or even timeouts
when the pool size is very small.
Using a dedicated executor for dev-server tasks should prevent the
above issues.

Fixes #20793

* nullify executor on shutdown
